Red lead is named dilead(II) lead(IV) oxide. Deduce its formula and the average oxidation number of lead.

A $Pb X_{3} O X_{4}$ ; $+ 10/3$
B $Pb X_{2} O X_{3}$ ; $+ 3$
C $Pb X_{3} O X_{5}$ ; $+ 10/3$
D $Pb X_{3} O X_{4}$ ; $+ 8/3$

Answer: D

Two Pb(II) and one Pb(IV) give

2 (+ 2) + 4 = + 8

, balanced by four

O X^{2 -}

:
